Wastewater Aeration Products

Evoqua's biological treatment and clarification business is rooted in the first chain systems applied to a wastewater plant. A REX® system from the Chain Belt Company, a precursor to Envirex®, was installed in 1910 and operated for almost seventy years with the support of our experts and aftermarket services. Envirex branded wastewater technologies from Evoqua has continued to be an innovative leader for equipment designs and services for aeration, biological treatment, anaerobic treatment, clarification, digestion, and separation treatment equipment for municipal and industrial applications.

DO2E Aerator / Mixers are high-efficiency all welded, heavy-duty PVC devices that are unique in several ways. DO2E’s patented products are designed to pull water from significant depths for aeration and mixing. By operating with low-pressure (<1.85 P.S.I.) high-volume airflow, these devices maximize energy efficiency. Our patented products are scalable and multi voltage.

Each aerator shall be capable of producing 3.0 lbs. of oxygen per nameplate horsepower per hour under normal conditions during aeration. Each 25 HP aerator shall be capable of pumping and mixing approximately 5,040,000 gallons per day under normal conditions and continuous operation

Aqua-Jet® aerators are installed in a wide variety of wastewater treatment schemes including activated sludge systems such as SBRs, MSBRs and extended aeration, as well as aerobic digesters, sludge holding, and equalization basins. It is also UL approved for TTHM stripping in potable water applications.

Reliable and efficient technologies are necessary for the treatment of municipal wastewater. Of the available technologies, the oxidation ditch process is well known for stable operation and reliable effluent quality.

The Aqua-Jet® surface mechanical aerator, manufactured by Aqua-Aerobic Systems, has been approved by Underwriters Laboratory (UL) to meet ANSI/NSF STANDARD 61 requirements for use in potable water applications.

Aerzen’s AERprocess Dissolved Oxygen Control is an integrated solution for controlling the dissolved oxygen (DO) concentration in the activated sludge treatment process and the blowers used to generate the process air flow requirement. The AERprocess system is able to maintain DO concentrations at their set points using a smart and efficient control strategy.

ClearBlu Environmental focuses on complete aerobic digestion of organic waste. This process is desirable over anaerobic digestion because it is fast, odor free, and prevents the need for any solids removal procedures. Aerobic digestion is desirable over DAF systems because it eliminates the need for costly chemical use and disposal. ClearBlu uses a unique aeration technology known as microbubble aeration, to achieve an aquatic environment which supports a bacteria population capable of complete digestion. This is the key difference over conventional technologies.
